Best AI visibility tools in 2026: how to choose by what they measure

Why is there no single best AI visibility tool?

If you are comparing the best AI visibility tools, start with a question instead of a list: what do you need to know? These products share a name and measure different things. A tool that answers one question can be silent on the next, so a ranking across all of them would compare things that do not line up.

A plain disclosure. MWY makes one of the tools listed here. The table reflects each vendor’s own pages as we read them on November 4, 2026. We did not buy or test the others. So you get no ranking, no “best for” verdict and no prices, which go stale. You get facts you can check yourself, and a way to choose.

Three questions sort the tools we read:

• (a) Can AI read and understand my site? Site checkers read your pages and report what stands in the way.
• (b) Do AI answers name my business? Answer trackers ask assistants questions and log the replies.
• (c) Can I see this inside an SEO suite? Large SEO products have added AI modules beside their rank tracking and keyword tools.

What does each kind of tool actually measure?

(a) Site checkers read your pages

A site checker opens your pages the way an AI bot would and tests them against a set of rules: are the bots allowed in, is the text in the HTML, is it clear who the business is, can an answer be lifted from the page. It asks no assistant anything, so it measures the inputs, the part you can change, and not whether any assistant names you.

Examples, in the vendors’ own terms: the MWY check, the GEO Content Check and AI crawlability check from Otterly.AI, the GEO Score Checker from Frase, the AI Search Health report in Semrush Site Audit, and the site audits in Scrunch.

(b) Answer trackers ask assistants questions

An answer tracker sends a set of questions to assistants on a schedule, stores the replies, then counts mentions, links and other businesses named. It measures the outcome, so this is the kind of tool that can show whether you are named. It needs many answers over time, because one reply proves little: the Peec AI documentation says “AI responses naturally vary day to day”, and the Ahrefs methodology post (updated February 26, 2026) calls its metrics “directional indicators, not exact traffic counts”.

A count of mentions shows what happened for the questions asked, not why. Our guide to AI visibility tracking covers how to run and read those rounds, and AI brand monitoring covers what the replies say about you.

(c) AI modules in large SEO suites

These do the same kind of tracking inside a product that also handles rankings and keywords. Ahrefs, Semrush and SE Ranking are the three in our table. Ahrefs and Semrush also keep databases of prompts they have already run, so you can look up a brand without writing a question, on questions someone else chose. Both also let you track your own.

Which tool answers which question?

Ten tools, listed alphabetically: the order is not a ranking. The letters refer to the three questions. AI Overviews and AI Mode are Google products. Assistants appear as each vendor lists them on the pages we read.

Three things to read:

• Coverage follows the plan. The assistants a vendor names may not all be on the plan you would buy. Otterly.AI sells three of them as add-ons, Frase adds them plan by plan, and Peec AI has you pick three at a time.
• “Free” means several things. A one-time check, a checker with a daily cap, a trial that ends, a free plan and an emailed report all carry the word. A trial may not run your own questions: Profound says trial users receive a recommended prompt set and cannot customize it.
• This is not the whole market. We stopped at ten tools whose facts we could read at the origin. A tool missing from the table says nothing about that tool.

Are the best AEO tools and best GEO tools something different?

Searches for AEO tools, GEO tools and AI visibility software lead to the same kinds of product. The HubSpot AEO page names GEO, AI visibility optimization and LLM optimization as other terms and says “these all refer to the same emerging discipline”.

The label tells you little about what a product measures. Use the three questions instead: does it read your pages, does it ask assistants, or does it do both?

Scores need the same care, because the word covers different sums. The Semrush AI Visibility Score combines topic coverage with how consistently a brand is mentioned. The HubSpot brand visibility score is how often your brand appears across your tracked prompts. The MWY score is weighted points across 24 items. Two scores from two tools are not comparable. Our guide to the AI visibility score covers what to ask about any one of them.

Why does it matter whether answers come from an API or the real interface?

A tracker can reach an assistant by two routes, and the route shapes the answer.

• The product interface. Software types the question into the public website, as a visitor would. The Peec AI documentation describes the result: “the platform decides which model to use and whether it runs a web search”, which it calls “the reality for a logged-out user”.
• The API. Software calls the service the company runs for developers. The OpenAI web search documentation, read on November 4, 2026, shows that the developer turns search on in the request, can make it required or leave it optional, and can pass an approximate user location. Those choices belong to whoever built the tool.

So three things can change between routes: the model that answers, whether a web search runs, and the location the assistant assumes. The sources can change too: Peec AI says their number and type in API responses can differ from those shown to real users. Otterly.AI and Profound make similar statements. All three sell tracking through the interface, so read this as vendors’ statements.

Neither route equals what your customer sees. The OpenAI help article “Searching the web with ChatGPT” says ChatGPT may use an IP address to estimate general location, and that saved location information may influence results when memory is on. Otterly.AI says answers differ by “session, location, and account settings” and calls its data “a neutral baseline”. A logged-in customer with a long history is a third case, and none of the pages we read claims to capture it.

What is not known: how large the gap is. We found no figure from the AI companies and no independent study. Surfer, which sells a tracker, reports that brand lists from APIs and from scraped apps overlapped only 15.5% to 23.8% (1,000 prompts, one sample each, August 2026). Gumshoe, which measures through APIs, argues that an earlier Surfer run used default API settings. MWY Pro would use APIs, so read this as a dispute between parties with a stake, ours included. What you can rely on is a trend from one route: compare this month with last month in the same tool, and do not compare one tool’s share with another’s.

Here is what each vendor says about its own route.

One tool can use both routes, so ask about each assistant, not the tool.

What should you ask any vendor before you pay?

Six questions show what you would get. Ask for the answers in writing.

Which assistants are covered on the plan I would buy? Check the assistants your buyers use against that plan, not the home page. In the table, Claude and Perplexity often sit on a higher plan or an add-on.

Do answers come from an API or the real product interface, for each assistant? A share measured one way cannot be compared with a share measured the other way.

How many questions, and how often? Peec AI gives the sum on its pricing page: monthly answers are “calculated by multiplying tracked prompts by active models and tracking frequency”. Schedules differ. Otterly.AI, Peec AI and Profound state daily runs. Scrunch collects new prompts daily for 14 days, then every 72 hours by default. MWY Pro would run 20 questions weekly.

Which location? Otterly.AI says “AI search results can differ significantly by region”. A plan can cap this: the first plan at Peec AI lists one country, and the Profound trial lists one region. If you serve one town, ask whether a city can be set. Semrush says its Brand Performance reports offer locations down to cities.

Can I read the raw answers? A count cannot show whether the description of your business is right, or which pages the answer leaned on. HubSpot says prompt tracking shows “the exact response”. Otterly.AI says you can view “the AI-generated answer text”. Ahrefs says “we store the raw responses”.

Does it say what to fix? A tracker reports what happened, and what to change next is a separate feature. Semrush lists “AI-generated strategic recommendations”, HubSpot lists “Prioritized AEO recommendations”, and the Frase plan table notes “AI Visibility does not auto-fix”. Ask what each recommendation rests on, and how you would check that a fix took effect.

You can paste this into an email to any vendor:

Before we buy, please answer in writing:

1. Which assistants does the plan we would buy cover?
2. For each one, do answers come from the API or the real product interface?
3. How many questions can we track, and how often does each one run?
4. From which location are questions asked? Can we set a city?
5. Can we read and export the full answers, with their sources?
6. Does the tool say what to fix, and on what evidence?

How do you choose without paying for three tools?

Match the kind of tool to what you need to know.

Then work through these steps.

Run a free page check first. Access problems sit upstream of everything else: an assistant cannot quote a page its bot cannot read.

Try one free answer check, and read what it is. Frase says each free probe runs three phrases, so “a free check is a snapshot”. HubSpot says its free grader asks each model how it characterizes your brand “based on its training data”, which is a different test from a tracked buyer question. Treat the result as a first look.

Write 10 to 20 buyer questions. Use their words, without your name in them. You cannot judge a plan’s allowance without this list.

Count the answers you need. As an illustration: 20 questions, 4 assistants and one round a week is 80 answers a week. Compare that figure with each plan’s allowance, in the unit that plan uses: prompts, checks, responses or credits.

Check what you already pay for. Some SEO suites include a quota or a snapshot: see the table.

Use a trial on your own questions. Where the trial allows it, run your list, then put a few questions to the assistants by hand and read both sets of answers side by side.

Where the figures come from

This page holds no prices and no performance figures for any tool, by design. Every count in it comes from the vendor named next to it, read on November 4, 2026.

• Ahrefs: the Brand Radar, pricing and free checker pages, the Brand Radar help article and the methodology post.
• Semrush: the Knowledge Base articles on the toolkit, its data sources, AI visibility features, Prompt Tracking and AI Search Health, plus the pricing and free checker pages.
• The other vendors: each pricing and product page, the Peec AI docs, the Otterly.AI help article on data collection, the Scrunch FAQ on collection methods, and the Profound comparison article with Peec AI, used only for what it says about Profound.
• OpenAI: the web search guide in its API documentation, and the help article “Searching the web with ChatGPT”.
• Surfer and Gumshoe: their own posts, updated October 4, 2026 and dated January 20, 2026.

We did not sign up, buy, or compare any tool’s output with another’s, so nothing here says how well a tool works. Where a vendor’s pages differ, as with the 7-day and 14-day trials on the Otterly.AI site, the table stays general. These products change monthly, so confirm any fact on the vendor’s page before you pay.

What the MWY checker does and does not answer here

The free AI visibility checker from MWY belongs to group (a). It reads public pages: the page you enter, up to 7 inner pages, robots.txt, sitemap.xml and llms.txt, as raw HTML without running JavaScript. It scores 24 items with fixed rules and no AI, so the same website gets the same result. You get the score, the three groups and the five items that matter most, with the reason, in a few seconds and with no sign-up.

The free check does not ask any assistant anything. It does open your home page under the names of the search bots of ChatGPT, Claude and Perplexity, but only to test whether a firewall blocks them. So it cannot tell you whether ChatGPT, Gemini, Claude or Perplexity name your business. It also stops short of the how-to: fixes for your platform are part of Pro.

Pro opens soon and is not on sale yet. MWY describes it as a monthly subscription per website, with all 24 items, fixes for your platform, snippets filled in with your details, a fix plan in order, and 20 buyer questions asked every week to ChatGPT, Gemini, Claude and Perplexity through their APIs with web search on. Answers through an API can differ from what one person sees in the app.

MWY does not promise that an assistant will name your business, and nobody outside the AI companies controls that. Use the checker for question (a). For question (b) today, use a tracker from the table or ask the assistants yourself.
